Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a concrete batching machine for concrete production. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, and water in a certain proportion, followed by stirring, molding, and hardening. It combines high strength, durability, and plasticity, and can be cast into various shapes as needed. It is widely used in construction, bridges, roads, and other engineering fields, and is an indispensable basic material in modern civil engineering. In the concrete production process at mixing plants and construction sites, batching machines are needed to measure the weight of aggregates such as sand and gravel, thereby controlling the raw material ratio and ensuring the quality of concrete production in batch production.

[0003] Existing concrete batching machines typically consist of several batching bins and a mixing bin. The batching bins weigh each raw material and then transport it to the mixing bin via a conveyor belt. When the raw material has a high water content, it becomes sticky, causing some of the raw material falling from the batching bin onto the conveyor belt. This results in the material falling off the conveyor belt after passing through the mixing bin. For example, the utility model patent with authorization announcement number CN220219104U discloses a concrete batching machine for concrete production, including a top frame. Two batching hoppers are fixedly connected to the top frame. A conveyor frame is provided below each of the two batching hoppers. The two conveyor frames are fixedly connected to the lower end of the top frame. Multiple support legs are fixedly connected to the lower end of the top frame. A connecting frame is fixedly connected between the multiple support legs. A mixing hopper is fixedly connected to the connecting frame. Two top covers are provided at the upper end of each of the two batching hoppers. The four top covers are rotatably connected to the upper end of the corresponding batching hoppers by hinges. A dust collection device is fixedly connected to the upper end of each of the two top covers located on the two batching hoppers. A storage device is provided through the upper end of each of the two top covers located on the two batching hoppers.

[0004] Although the aforementioned concrete batching machine prevents dust from being blown out of the hopper when raw materials are added by installing a dust collection device on the hopper, it cannot scrape off the raw materials adhering to the conveyor belt during use. This results in raw materials spilling outside the mixing bin, requiring manual cleaning later.

[0005] Therefore, it is necessary to develop a batching machine for concrete production to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a batching machine for concrete production that can scrape off and collect raw materials adhering to the surface of the conveyor belt, thereby maintaining the cleanliness of the conveyor belt surface and preventing raw materials from spilling everywhere.

[0009] Furthermore, conveyor rollers are provided at both ends of the conveyor belt, and the conveyor rollers are rotatably connected between the two baffles; a plurality of support rollers are rotatably connected between the two baffles, and the support rollers support the conveyor belt.

[0010] Furthermore, the scraping and collecting assembly includes a collecting box with an open top surface and a side wall fixedly connected to the second fixed frame. The two opposite inner walls of the collecting box are detachably connected to fixed plates, and the top surface of the fixed plates is provided with scraping components.

[0011] Furthermore, the scraping component includes a movable plate, which is slidably connected to the fixed plate. Two inclined support rods are fixedly connected to both ends of the movable plate. An mounting plate is fixedly connected between the two support rods near the mixing chamber. A rubber scraper is fixedly connected to the top surface of the mounting plate. A brush roller is rotatably connected between the other two support rods. Both the brush roller and the rubber scraper are in contact with the bottom surface of the conveyor belt.

[0012] Furthermore, a plurality of spaced sliding rods are fixedly connected to the top surface of the fixed plate, the sliding rods passing through the movable plate and slidably connected thereto; a compression spring is provided between the movable plate and the fixed plate, the compression spring being sleeved on the sliding rod; a limit block is fixedly connected to the top end of the sliding rod.

Detailed Implementation

[0023] The core of this utility model is to provide a batching machine for concrete production, which can scrape off and collect raw materials adhering to the surface of the conveyor belt, thereby maintaining the cleanliness of the conveyor belt surface and preventing raw materials from spilling everywhere.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In one specific embodiment of this utility model, such as Figure 1 As shown, the system includes a rectangular first fixed frame 1, with vertically arranged support legs 2 fixedly connected to the four corners of the first fixed frame 1. Two batching bins 3 are fixedly connected to the inner wall of the first fixed frame 1 at intervals. A horizontally arranged rectangular second fixed frame 4 is fixedly connected to the middle of the support legs 2. Baffles 5 are fixedly connected to both ends of the top surface of the second fixed frame 4. Conveyor belts 6 are arranged between the inner walls of the two baffles 5, and the two conveyor belts 6 are respectively positioned opposite the discharge ports at the bottom of the two batching bins 3. A mixing bin 7 is arranged between the two conveyor belts 6, and the top of the mixing bin 7 is fixedly connected to the bottom surface of the second fixed frame 4. Scraping and collecting components 8 are arranged on both sides of the bottom surface of the second fixed frame 4, and the scraping and collecting components 8 scrape the bottom surface of the conveyor belts 6. An electric gate valve is installed at the discharge port at the bottom of the batching bin 3, and a weight sensor is installed in the batching bin to measure the weight of the sand and gravel raw materials. This is existing technology and will not be described in detail here.

[0027] The raw materials, after being metered by the batching bin 3, fall onto the conveyor belt 6 and are transported by the conveyor belt 6 to the mixing bin 7 for collection. The scraping and collecting component 8 is close to the bottom surface of the conveyor belt 6 and scrapes off and collects the adhering raw materials as the conveyor belt 6 rotates, preventing the raw materials from spilling outside the mixing bin.

[0028] In one specific embodiment of this utility model, such as Figure 1 As shown, conveyor rollers 9 are provided at both ends of the conveyor belt 6. The conveyor rollers 9 are rotatably connected between two baffles 5. One of the conveyor rollers is connected to a geared motor through a coupling to provide power to the conveyor belt. Several support rollers 10 are rotatably connected between the two baffles 5 at intervals. The support rollers 10 are in contact with the inner top surface of the conveyor belt 6 to support the conveyor belt 6 and prevent the conveyor belt from sagging due to the weight of the raw materials.

[0029] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the scraping and collecting assembly 8 includes a collecting box 801. The top surface of the collecting box 801 is open and the side walls are fixedly connected to the second fixed frame 4. The two opposite inner walls of the collecting box 801 are detachably connected to fixed plates 802. The top surface of the fixed plates 802 is provided with scraping components.

[0030] The collection box 801 collects the materials cleaned by the scraper, preventing spillage. The detachable design of the fixing plate 802 facilitates the disassembly of the scraper for maintenance and replacement, reducing the difficulty of equipment maintenance.

[0031] Specifically, the scraping component includes a movable plate 803, which is slidably connected to a fixed plate 802. Two inclined support rods 804 are fixedly connected to both ends of the movable plate 803. An mounting plate 805 is fixedly connected between the two support rods 804 near the mixing chamber 7. A rubber scraper 806 is fixedly connected to the top surface of the mounting plate 805. A brush roller 807 is rotatably connected between the other two support rods 804. Both the brush roller 807 and the rubber scraper 806 are in contact with the bottom surface of the conveyor belt 6.

[0032] When the conveyor belt 6 is running, it is first scraped by the rubber scraper 806, and then cleaned a second time by the brush roller 807. The double scraping structure improves the cleanliness of the conveyor belt. The brush roller 807 rotates passively with the conveyor belt 6, reducing friction damage with the conveyor belt 6.

[0033] Specifically, a number of spaced-apart slide rods 808 are fixedly connected to the top surface of the fixed plate 802. The slide rods 808 pass through the movable plate 803 and are slidably connected to it. A compression spring 809 is provided between the movable plate 803 and the fixed plate 802, and the compression spring 809 is sleeved on the slide rod 808. A limit block 810, which is a stainless steel circular plate, is fixedly connected to the top of the slide rod 808 to prevent the movable plate 803 from detaching from the slide rod 808.

[0034] By compensating for the elasticity of the compression spring 809, the scraper can adapt to slight vibrations or thickness deviations of the conveyor belt 6, and always maintain a stable scraping pressure. This avoids both insufficient pressure leading to incomplete scraping and excessive pressure damaging the conveyor belt 6, thus extending the service life of the conveyor belt 6.

[0035] Specifically, two pressure rollers 811 are rotatably connected between the inner walls of the two baffles 5. The two pressure rollers 811 press the conveyor belt 6 tightly onto the rubber scraper 806 and the brush roller 807, respectively. The pressure rollers 811 make the conveyor belt 6 fit tightly against the rubber scraper 806 and the brush roller 807, respectively, thereby improving the cleaning effect on the conveyor belt 6.

[0036] In one specific embodiment of this utility model, such as Figure 3As shown, a fixing block 812 is fixedly connected to the inner wall of the collection box 801. The top surface of the fixing block 812 has a slot 813 that matches the fixing plate 802. Both ends of the fixing plate 802 are fixedly inserted into the slot 813. A box door 814 is hinged to the side wall of the collection box 801 away from the mixing chamber 7. The fixing plate 802 is quickly inserted and fixed inside the collection box 801 through the slot 813. It can be disassembled and assembled without tools. The scraper can be taken out for cleaning and maintenance by opening the box door 814.

[0037] Specifically, a collection box 815 is provided inside the collection box 801, and an opening 816 is provided through one side wall of the collection box 801 to facilitate the removal of the collection box 815. The collection box 815 can be removed from the collection box 801 by pulling it out, facilitating quick cleaning of the collected raw materials.

[0038] Working principle of this utility model: When using this utility model, raw materials such as sand and gravel are first added to two batching bins 3. After the weight sensor reaches the measurement standard, the electric gate valve at the bottom of the batching bin is opened, and the raw materials fall into the conveyor belt 6 directly below. The reduction motor of the conveyor roller 9 is started, driving the conveyor belt to transport the raw materials to the middle mixing bin 7. At the same time, the scraping and collecting component 8 works synchronously. The bottom surface of the conveyor belt 6 first contacts the rubber scraper 806. The compression spring 809 pushes the moving plate 803 to make the rubber scraper 806 fit tightly against the conveyor belt 6, scraping off most of the adhering raw materials. Then the conveyor belt 6 passes through the brush roller 807. The brush roller 807 rotates passively with the conveyor belt 6 to sweep away the remaining fine raw materials. The cleaned raw materials fall into the collection box 815 in the collection box 801. The raw materials can be recycled and reused by periodically removing the collection box 815. When maintaining the scraping component, the box door 814 of the collection box 801 is opened, and the fixing plate 802 is pulled upward to remove the rubber scraper 806 or replace the brush roller 807.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.
